`FA 12` peach tree

ABSTRACT

A new peach variety, Prunus persica, (hereinafter referred to as the `FA 12` peach tree) which was developed by Annette and Randy Bjorge in a breeding program at Fruit Acres Farm in Coloma, Mich., having the following combination of unique and desirable features: 
     1. A substantially round fruit with an attractive bright red blush coloration covering 90 to 100% of the fruit at maturity. pg,2 
     2. A fruit maturing 5 days later than the `Redhaven` peach. 
     3. A fruit with excellent storage and shipping qualities. 
     4. A tree and fruit with good resistance to bacterial spot. 
     5. A fruit with flesh that does not brown when cut. 
     6. A fruit and blossom that is very hardy.

ORIGIN OF THE VARIETY

The new variety of peach tree `FA 12` was developed by Annette and RandyBjorge in a peach breeding program at Fruit Acres Farms, 2559 FridayRoad, Coloma, Mich. 49038. The `FA 12` peach tree was developed as afirst generation cross between `Fayette` and `Newhaven`, twoestablished, non-patented, commercial varieties. The parent tree wasgrown and maintained in a peach tree breeding orchard in Fruit AcresFarms. This new and distinct variety of peach tree has been asexuallypropagated by budding at Fruit Acres Farms in Coloma, Mich. The asexualpropagation demonstrates that such reproduction of the characteristicsof the tree are consistent and are established and transmitted throughsucceeding generations.

SUMMARY OF THE VARIETY

The new and distinct variety of peach tree is of large, upright growthwith medium density and is a regular and very productive bearer ofpeaches. The fruit of the new variety is characterized by its round,substantially 90 to 100% bright red blushed, fruits that present a veryattractive appearance. The fruits have firm flesh and are resilient tothe extent that they may be handled and packaged mechanically withoutdamaging the same for shipment. This results in less spoilage and agreater market value. The flesh of the fruits of the new variety doesnot brown when cut. The fruits of the new variety have a recessed pistilpoint which avoids damage during picking and handling. The tree andfruits of the new variety exhibit good resistance to Bacterial Spot. Thefruit matures in the beginning of the peach growing season inSouthwestern Mich. It ripens 5 days after the established commercialvariety, `Redhaven`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show typical specimens of the new varietyin color as nearly true as it is reasonably possible to make the same incolor illustrations of this character. The specimens were photographedin Van Buren and Berrien counties of Southwestern Michigan.
